Because in English, describing words or actions usually go before the 
thing they describe or act on. You say "weighted normals", not "normals 
weighted". You tell POV to weight the normals or to use weighted 
normals, not to use normals weighted.

Allowing a boolean after "weighted_normals"(or "weight_normals", or...) 
so you could specify on or off...um, that's all I could think of right 
now. I think I mentioned all the ones I thought of.

Yes, I was thinking of that...some interesting possibilities. And if you 
use warps to specify the deformations, you could control the textures 
yourself...your patch looks like it could be very fun just to play 
around with. :-)

I'm not sure what exactly you mean...I would assume that parts of the 
surface where the deformation is undefined simply aren't deformed. If 
you want only part of the object to be deformed, you should probably use 
a union of a deform object with ordinary objects.
BTW, multiple deformations would also be useful...just allow them to be 
applied one after the other, which should be very easy to do if you use 
warps. That way you could make a twisted, turbulated box being sucked 
into a black hole. :-)
deform {
    box {<-1,-1,-1>, < 1, 1, 1> texture {Texture}}
    deformation {turbulence 0.2}
    deformation {twist y, 8}
    deformation {black_hole ...}
    accuracy 0.05
    normal_accuracy 3, 0.01
    weighted_normals on
}

Oops, that should have been "deformation {twist y, 8}".
